DONALD E. BURGER, 0F MOUNT VERNON, NEW YORK.

INDICATOR.

Application filed November 21, 1917. Serial No. 203,165.

To all whom it may concern.'

Be it known that I, DONALD E. BURGER, a citizenvof the United States,residing at Mount Vernon, in the county of `Westchester and State of NewYork, have invented certain new and useful Improvements in Indicators,of which the following is a specification, reference being had to theaccompanying drawings.

This invention relates to an improved indicator and has for its primaryobject to provide a very simply constructed, efficient and serviceableindicating device which may be advantageously used as a street orstation indicator for cars and other vehicles, or which may be employedin connection with display advertising.

It is one of the more particular objects of the invention to provide twosets of rolls mounted within a suitablel casing and geared together,each roll set carrying a display web the ends of which are connected tothe respective rolls, an actuating spring for each set of rolls, andinterchangeable means to operatively connect the springs with one of therolls in each set.

It is another important object of my invention to provide electricallycontrolled means with which means'on one of the webs is adapted to coactwhereby the webs are held against movement.

It is a further general object of my invention to provide a device forthe above purpose which is highly efficient and reliable in itsoperation and wherein the several parts are very compactly arranged sothat the device will occupy but little space.

With the above and other objects in view the invention consists in theimproved construction, combination and arrangement of the several partsas will be hereinafter more fully described, subsequently claimed andillustrated in the accompanying drawings in which similar referencecharacters desigl nate corresponding parts throughout the several viewsand wherein:

Figure 1 is a vertical sectional View through one end of the casing ofthe indicator showing the arrangement of the indieating tapes thereinand the actuating means for said tapes.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1; A

Fig. 3 is a section taken on the line 3 3 of Flg. 1;V

Fig. 4 is a detail end elevation;

Fig. 5 is a section taken on the line 5 5 of Fig. 1;

Fig. 6 is a side elevation of the indicator;

Fig. 7 is a fragmentary perspective View of one of the webs illustratingthe relative Aarrangement of the solenoid core in the movement of theweb;

Fig. 8 is a similar view showing one of the tapes or projections on theweb engaged with the solenoid core when the web is stationary;

Fig. 9 is a sectional view through the solenoid; and

Fig. V10 is a detail elevation of the winding key for the roll springs.

Referring in detail to the drawings, 5 and 6 designate the top andbottom walls respectively, of a relatively narrow sheet metal casingwhich are connected at their ends by integral end walls. One of theseend walls of the casing designated 'l' is formed contiguous to the topand bottom walls with cylindrical lateral extensions 8. The ends ofthese extensions have inwardly pressed walls 9, each of which iscentrally formed with an inwardly projecting tubular boss 10.

The opposite sides of the case are closed by means of the doors 11 whichare hingedat spaced points along their lower edges to the bottom wall 6of the case as shown at 12. The free longitudinal edges of these doorsare provided with slots to receive rotatable latch elements 13 suitablymounted on the angular fianges 5 which are formed on the longitudinaledges of the top wall 5.

Within the case and at each end thereof a vertically disposed frameplate 13 is arranged, said plates'being fixed at their ends to the topand bottom walls of the case. Each of these plates is provided in one ofits edges and adjacent its upper and lower ends with the correspondinglylocated inwardly and downwardly inclined bearing seats or notches 14 andsimilar notches 15 are also provided in the other vertical edges ofthese frame plates, the latter notches however, being spaced from thenotches 14. The ends of rolls 16 are engaged in the bearing seats 14 andto these rolls the ends of a web 17 are attached in any suitable manner,Similar rolls 18 are engaged at their ends inthe bearing seats 15 and asecond web 19 is attached at Vits ends to these latter loro zio

rolls. AThese Webs are opposed to the sight openings 20 in the hingeddoors 11 of the case.

One ofthe upper rolls 16 and one of the lower rolls 18 are respectivelyin aXial alinement with the cylindrical projections 8 on theiend wall.of .the case and the ends of said rolls which are opposed -to theextensions 8 are formed vvith" rectangular notches 21. The rolls 16 and18 are operatively connected by means of Ethe gears 22.

Within each of the extensions 8 on the end Wall ofthe case, a bearingmember 23 is'arranged and secured to the Wall of said extension. :Inthis bearing member, a rectangular sleeve 24 is rotatably nionnted. Oneend of a spirally coiled .spring V25 is fixed to this sleeve and theother end thereof is suitably attached, as at 26, to the bearing. y27designates akey A,which has a rectangular shank 28 reduced at one of'itsends as at 2,9, the other end of said shank being cylindricallyfo-rmed,as shown at 30. This key isadapted to be inserted through eitherof the bosses 10 and the rectangular portion of the key shank engagedWithin `the sleeve 2.4 lthereduced"end`29 ofl the key shank fitting intothe notch 2 1 in'the end of the roll shaft 16l or 18 vas the case maybe.

'illlie Web l17 isfprovided from one l.of its edges With the spacedlaterally projecting tabs or extensions lollfsaid tabs being spaced inaccordance'ivith the arrangement of the indicia upo'nthe face of theweb. The frame bars 13 'are connectedby an angular rail 32 andupoii thisrail a 'solenoid 33 is mounted. T-he corerl of this solenoid is normallyprof jected by means of the l.coil spring 35, `as clearly shown in Fig.i9 of thedravvings into the pathofinoveinent of the tabs or eX-tensionsl on the'iveh 17. Thesolenoid is of course arranged in asuitable circuit, not sho'vvn, a switch `Which niay be actuatedautomatically upon the opening of a door, or by'nleans'ofa lever, pullcord, or other eiliteible deviee- Having now described the constructionandf relativel arrangement o f the several parts of my improvedindicator, its operation Will be understood Las -i'follovvs. After therolls 1 6' erlfl 18 eerryine the Weloe havebeen in- Sertetlinto thebearing eeete in the freine. upri'gh'tsv 13 and the doors of the caseclosed, the lie'yv Slienlr 28 ie ineerted into one of the Sleeves.' 2i"but the end of this .key Sllink ie not eneegeol in Ethe noten 2l of theadja- Cent web roll- The keyis then turned to Wind the spring and placeit under tension. The. lreyY ieftlierly nnelierl farther in to engagethe end 2,9 there o1 inthe notch 21 of the roll. Upon. the release ofthe lrey, tire Spring Will etert to unwind and rotate the rolls 16 and18 vrliereby the Webs are inoved- This Inovernent 'will eontinoe untilot the project# ing tabs 31 on the Webs L7 comes into engagenient Withthe solenoid core 34. When it is desired to change the street number orother indicia displayedlfby the web, the circuit is closed, to energizethe solenoid Wherefbyfthe core is retracted out of the path of -the tab31 so that the web 17 may be moved. A corresponding movement is ofcourse transmitted to the web 19 through the medium of the gears 22. Theclosing of the circuit is only momentary, and thesolenoid coreisretnrned to its normal position-.by the spring 3,5 so that When thetab 31 contacts with the solenoid core the movement of the Webs Will bestopped, thereby displaying ythe successive names on the Webs lthroughthe reepeetivo sieht openings .2Q- Thie operation continues until theivebs'are entirely Wound upon one roll in each-set, as forfnstance whentheend of the route traversedbythe car or vehicle is reached. The keyvis'then Withdrawn from the bearing sleeve `211 and inserted intotheother 4of the bearing sleeves So es to `Wind the Other Spring VThekey ie then operatively enge-sed Wthttheend of the edieeerlt Web rollinthe/ manner .above stated, and upon thereleasethereof vthe Webs eremoved in a reverse direeton ,to `the former direotion of movement, thesolenoid Core operating to Control Such movement of the Webs as will beclearly understood `from the foregoing deeerintion.
